I have a table with 3 columns: name text start_id integer end_id integer
start_id and end_id are ranges which must not overlap but can have gaps between them. Is it possible to formulate a table check constraint that can verify that either id does not fall within an existing range at insert time? IE prevent overlaps during insert?
